Django docusignpythonsdk-API异常400-'；错误请求'；

关于将Docusign的pythonsdk与我公司的web应用程序集成的问题，我发表了几篇文章。基本上，我所做的是让用户填写表单，在用户单击submit按钮后，weasyprint从我创建的html模板生成pdf，并将客户信息放置在正确的位置。然后，我希望DocuSign使用新生成的PDF向用户发送一封电子邮件，让他们在表单上签名，并将其发送到我公司的电子邮件帐户。以下是我尝试将Python的SDK集成到Django web应用程序中的方法：

def Signview(request):
    loa = LOA.objects.filter().order_by('-id')[0] # This is pulling the information about the user from a model in my database
    username = "myusername@docusign.com"
    integrator_key = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
    base_url = "https://demo.docusign.net/restapi"
    oauth_base_url = "account-d.docusign.com"
    redirect_uri = "http://localhost:8000/path/to/redirecturi"
    private_key_filename = "path/to/pKey.txt"
    user_id = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
    client_user_id = 'Your System ID' # This is the actual string I am using for this variable

    # Add a recipient to sign the document
    signer = docusign.Signer()
    signer.email = loa.email
    signer.name = loa.ainame
    signer.recipient_id = '1'
    signer.client_user_id = client_user_id

    sign_here = docusign.SignHere()
    sign_here.document_id = '1'
    sign_here.recipient_id = '1'
    sign_here.anchor_case_sensitive = 'true'
    sign_here.anchor_horizontal_alignment = 'left'
    sign_here.anchor_ignore_if_not_present = 'false'
    sign_here.anchor_match_whole_word = 'true'

    sign_here.anchor_string = 'Sign Here'
    sign_here.anchor_units = 'cms'
    sign_here.anchor_x_offset = '0'
    sign_here.anchor_y_offset = '0'
    sign_here.tab_label = 'sign_here'
    tabs = docusign.Tabs()
    tabs.sign_here_tabs = [sign_here]

    # Create a signers list, attach tabs to signer, append signer to signers.
    # Attach signers to recipients objects
    signers = []
    tabs = tabs
    signer.tabs = tabs
    signers.append(signer)
    recipients = docusign.Recipients()
    recipients.signers = signers

    # Create an envelope to be signed
    envelope_definition = docusign.EnvelopeDefinition()
    envelope_definition.email_subject = 'My email subject'
    envelope_definition.email_blurb = 'My email blurb'

    # Add a document to the envelope_definition
    pdfpath = "path/to/mypdf.pdf"
    with open(pdfpath, 'rb') as signfile:
        file_data = signfile.read()
        doc = docusign.Document()
        base64_doc = base64.b64encode(file_data).decode('utf-8')
        doc.document_base64 = base64_doc
        doc.name = "MyDoc_Signed.pdf"
        doc.document_id = '1'
        envelope_definition.documents = [doc]
        signfile.close()
    envelope_definition.recipients = recipients
    envelope_definition.status = 'sent'

    api_client = docusign.ApiClient(base_url)

    oauth_login_url = api_client.get_jwt_uri(integrator_key, redirect_uri, oauth_base_url)
    print("oauth_login_url:", oauth_login_url)
    print("oauth_base_url:", oauth_base_url)

    api_client.configure_jwt_authorization_flow(private_key_filename, oauth_base_url, integrator_key, user_id, 3600)
    docusign.configuration.api_client = api_client

    auth_api = AuthenticationApi()
    envelopes_api = EnvelopesApi()

    try: #login here via code
        login_info = auth_api.login()
        login_accounts = login_info.login_accoutns
        base_url, _ = login_accounts[0].base_url.split('/v2')
        api_client.host = base_url
        docusign.configuration.api_client = api_client

        envelope_summary = envelopes_api.create_envelope(login_accounts[0].account_id, envelope_definition = envelope_definition)

        print(envelope_summary)
    except ApiException as e:
        raise Exception("Exception when calling DocuSign API: %s" % e)
    except Exception as e:
        print(e)
    return HttpResponse({'sent'})

但是，这是我运行此代码时收到的错误：

我已经在我的DocuSign admin页面上用我的integrator密钥输入了重定向URI，我已经转到链接并点击“accept”，以便获得开始签名的许可，但是，这是我遇到的问题，我不确定出了什么问题。这里的一位同事向我提供了这个解决方案，他告诉我，代码应该可以工作，而且可能是DocuSign管理端的一些我没有做的事情。这里的代码有什么明显的错误吗

提前谢谢

很难定义管理面板中的错误。您可以尝试完成以下步骤来定义错误：

检查管理员和代码中的重定向uri是否相同

在管理面板中检查用户id是否与API用户名相同（这是我的问题）

确保路径/to/pKey.txt中的私钥与管理面板中的私钥相同

---

我希望它能帮上忙。

非常感谢！我不能100%确定具体的修复方法是什么（我将用户id更改为错误的，然后又将其更改回来，它就成功了）。然而，我现在有它在文件中的电子邮件被列为已发送，但我从来没有收到过电子邮件。我仍然在使用演示，当我使用演示版本时，我不应该能够收到电子邮件吗？或者可能还有其他问题？我确实点击了“重发”，但我仍然没有收到。这是因为我没有为信封创建“通知”变量吗？这对信封收件人收到的电子邮件是必要的吗？不，您可以在演示模式下使用所有功能。您确定电子邮件是正确的吗？当您从DocuSign面板创建演示信封时，它也没有发送电子邮件？尝试设置不同的客户端\用户\ id，从中发送我检查，电子邮件肯定是正确的。但是，我确实尝试了另一次发送，这次将客户端用户id从“您的本地系统id”更改为收件人的电子邮件。没有任何变化，但是，仍然没有任何人收到电子邮件。即使是Docusign那边的人也不确定到底出了什么问题。我可能会发表另一篇文章来解决这个问题。
